After reading the review on Square Meal, decided to book a table for 25 at Delfino's on a Saturday night. The person on the phone was really nice and flexible (as it was orginially 20 people). On the night, we were booked in for 8pm, but we had some people come in a bit late (8:30 -9). We were rushed into ordering food and felt hurried by the staff, although we had ordered drinks right from the start (lots of wine and beer), so couldn't see the issue of us waiting for everyone to arrive (especially as the restaurant wasn't that busy!). Food was good, everyone enjoyed their pizzas, and the tiramisu went down a treat. They even sang Happy Birthday to the birthday boy and everything. However, when it came down to split the bill between 25 people, the staff proved incompetent and rude. All 25 people paid (and had the receipts from their cards to prove it), yet they insisted that one person didn't pay – when we said that if was due to their lack of organisation and it would have to come out of the optional tip, one of the waitresses turned very rude and even said : 'Well, that's the last time we take a booking from you'. Being threatened wasn't a very nice experience, especially as there's lots of pizza places to go to in London! To say the least, they made a lot of money out of us that evening and yet they managed to lose the custom of 25 people who won't be going back there.
